Answer:
y = -8
Step-by-step explanation:
There is no x-variable as that would make the line tilt.
Hope this helps! Have a nice day!
3-4z=-5+8z
Add 5 to both sides
8-4z=8z
Add 4z to both sides
8=12z
Divide both sides by 12
z=12/8
Simplify
z=3/2
Factor the left side:
x (19+ r)= -37 + w
x= (-37 + w) / (19 +r)
Slope formula : (y2 - y1) / (x2 - x1)
(2,4)...x1 = 2 and y1 = 4
(5,10)...x2 = 5 and y2 = 10
now we sub and solve
slope = (10 - 4) / (5 - 2) = 6/3 = 2
The slope of the line is 2....and this is basically saying that Jan runs 2 laps every minute
